New evidence finds standardised cigarette packaging may reduce the number of people who smoke as UK legislation bans the use of branding on all cigarette packets from May 2017.

A Cochrane Review published today finds standardised tobacco packaging may lead to a reduction in smoking prevalence and reduces the appeal of tobacco.

According to the World Health Organisation, tobacco use kills more people worldwide than any other preventable cause of death. Global health experts believe the best way to reduce tobacco use is by stopping people starting to use tobacco and encouraging and helping existing users to stop.

plain-packs-620-x-348-heroThe introduction of standardised (or ‘plain’) packaging was recommended by the World Health Organisation, Framework Convention on Tobacco Control (WHO FCTC) guidelines. This recommendation was based on evidence around tobacco promotion in general and studies which examined the impact of changes in packaging on knowledge, attitudes, beliefs and behaviour. Standardised tobacco packaging places restrictions on the appearance of tobacco packs so that there is a uniform colour (and in some cases shape) with no logos or branding apart from health warnings and other government-mandated information, and the brand name appears in a prescribed uniform font, colour and size.

From next month, UK legislation on standardised packaging for all tobacco packs comes into full effect.

Australia was the first country in the world to implement standardised packaging of tobacco products.  The laws, which took full effect there in December 2012, also required enlarged pictorial health warnings.

A team of Cochrane researchers from the UK and Canada have summarised results from studies that examine the impact of standardised packaging on tobacco attitudes and behaviour. They have today published their findings in the Cochrane Library.

Electronic cigarettes could have a huge effect on public health | Marcus Munafo, University of Bristol

June 20, 2016 2.17pm BST – Marcus Munafo – The Conversation

Tobacco still kills 6m people around the world every year. Despite huge public health efforts to help people quit and prevent young people starting, smoking remains the single greatest cause of ill health and premature death. And even with restrictions on tobacco advertising and smoking in public places, many young people continue to take up smoking. The situation is even worse in poorer countries, where support to stop smoking is limited, and tobacco control policies weaker.

So in light of this, how should we view the increasing popularity of electronic cigarettes?

image-20160620-8853-1qda1qwThe gadgets deliver a nicotine hit by heating a nicotine-containing propylene glycol (e-liquid) to create an aerosol (usually called “vapour”), which is inhaled. Put simply, they deliver nicotine almost as effectively as a conventional cigarette, but without the vast majority of other chemicals present in tobacco smoke (either from the tobacco itself, or as a result of the burning process).

A whole culture is emerging around “vaping”. Many devices offer a range of power settings, and a vast array of e-liquids is on offer, with varying nicotine contents and flavours. Enthusiasts often apply modifications to their devices, and engage in “cloud chasing” – competing to produce the largest and most interesting clouds of vapour. And yes, young people are experimenting with e-cigarettes (in the same way that they have always experimented with pretty much everything), although at the moment there is no strong evidence this is leading to subsequent cigarette use, or even long-term e-cigarette use.

The rapid growth in use of e-cigarettes, especially among smokers trying to cut down or quit, has taken the public health community and the tobacco industry by surprise. Both are struggling to catch up. Health professionals are hurrying to carry out research to develop evidence-based guidelines and policies. Meanwhile, the tobacco industry is buying up e-cigarette companies and introducing its own products onto the market.

So how concerned should we be about this emerging and disruptive technology?

Should we encourage existing smokers to use e-cigarettes to help them stop smoking, even if this means they continue using nicotine long-term? In the United Kingdom there is some consensus that smokers should be encouraged to use e-cigarettes if they feel they might help, and the National Centre for Smoking Cessation and Training is supportive of their use. Part of the reason many vapers feel so passionately about the subject (and react strongly when they feel that vaping is being unfairly attacked) is that for the first time, through the use of e-cigarettes, they have felt able to take control of their nicotine habit, stop smoking, and reassert some control over their health, without being medicalised in the process.

But a problem remains in the lack of information on the possible harm of e-cigarettes. This is unlikely to change any time soon, since the health effects of tobacco use can take several decades to emerge, and it’s probable the same will be true for e-cigarettes. Nothing is entirely risk-free, but the vastly reduced number of chemicals present in e-cigarette vapour compared to tobacco smoke means we can be confident that vaping will be much, much less harmful than smoking.

Heartening evidence

As part of the investigation into the effects of e-cigarettes, we investigated how the cells found in the arteries of the heart, known as human coronary artery endothelial cells, responded when they were exposed to both e-cigarette vapour and conventional cigarette smoke. We found the cells showed a clear stress response from the cigarette smoke, but not from the electronic cigarette. This suggests tobacco smokers may be able to reduce immediate tobacco-related harm by switching from conventional cigarettes to e-cigarettes.

Many people find it difficult to function without their first caffeine hit of the day. But no one is seriously calling for coffee shops to be dismantled or regulated. Nicotine is addictive, but much less so on its own than in tobacco, where other chemicals enhance its effect. At the doses consumed by vapers the harm is likely to be very low (although we need to continue to research this), and many vapers actually gradually move to zero nicotine content e-liquids, even while continuing to vape.

Of course, we may end up with a large population of long-term nicotine users who use e-cigarettes to deliver nicotine rather than cigarettes, but all of the evidence at the moment suggests that this population will almost entirely comprise ex-smokers. This would produce a vast public health gain.

We must be careful not to restrict smokers’ access to e-cigarettes, or over-state the potential harm of their use, if this will put people off making the transition from smoking to vaping. To do so would deny us one of the greatest public health improving opportunities of the last 50 years.

New research from ASH Wales Cymru shows e-cigarettes are not a gateway to smoking for young people

New research released today shows no evidence that e-cigarettes are a ‘gateway’ for young people to start smoking. The annual survey, by tobacco control campaign group, ASH Wales Cymru, questioned more than 830, 11 to 18 year olds across Wales.

free-vape-vector-icons-2
For the third year running the survey shows there is no link between youths vaping and starting smoking tobacco.

It has been a concern among health professionals since the rapid emergence of e-cigarettes that they would ‘renormalise’ smoking and act as a ‘gateway’ towards tobacco for young people.

Of the young people who reported using both e-cigarettes and tobacco cigarettes at some point, 90% had used tobacco first, suggesting the absence of any ‘gateway’ theory. The report confirms e-cigarette use is confined to current smokers or ex-smokers and they are rarely used among ‘never’ smokers.

It also showed more than 30% of the e-cigarette users had quit smoking altogether. Reasons for using e-cigarettes varied from taste, to friends using them, to wanting to know what they were like.

Young people from the poorest parts of Wales were 25% more likely to have used an e-cigarette compared to their counterparts in the least deprived areas of the country.

These statistics around use by young people match recent results around adult usage from the Welsh Health Survey 2015.

This was the first time the Welsh Health Survey had looked at e-cigarette use. It revealed that 6% of over 16’s stated they currently use an e-cigarette – 140,000 of the Welsh population. Use among never smokers was negligible at 0.06%.

Suzanne Cass, Chief Executive of ASH Wales:

“For the third year in a row our research confirms young people are not using e-cigarettes if they’ve never smoked before.”

“E-cigarettes can contain highly addictive nicotine and there is no need for young non-smokers to use the devices. We are pleased to see these latest results confirm that e-cigarettes are being used as a smoking cessation device, similar to nicotine patches or gum and at the moment are not acting as a gateway towards tobacco.  E-cigarette users are now reducing the harm to their bodies caused by poisonous and cancer-causing tobacco smoke.”

Professor Linda Bauld from the University of Stirling and UK Centre for Tobacco and Alcohol Studies:

“There is a lot of confusion about the relationship between e-cigarettes and smoking in young people. Surveys from other countries do keep claiming there is a link despite youth smoking rates continuing to fall in the countries where these studies take place. This new data from Wales should reassure people that although young people are experimenting with e-cigarettes, we are not seeing regular use in never smokers. Meanwhile, youth smoking rates in Wales continue to decline, which is key to preventing cancer and other diseases that smoking causes.”

Ruth Coombs, Head of British Heart Foundation (BHF) Cymru:

“We are pleased that latest ASH Wales Cymru findings highlight encouraging trends to show that young people in Wales are not turning to e-cigarettes as a way to start smoking but rather as a way to reduce harm caused by intake of tobacco by cigarettes.”

 

Principal Findings:

  •  In terms of awareness of e-cigarettes, a large majority of respondents (90.7%) were aware of e-cigarettes. When stratified by age and gender the awareness of e-cigarettes remained extremely high. As many as 88.5% of respondents under the age of 13 were aware of what an e-cigarette is.
  • The most common sources of finding out about e-cigarettes were: seeing strangers using them in public (45.9%), reading or hearing about them on the internet or social media (42.6%), being told about them by friends (42.5%), and seeing them or hearing about them in the media (42.5%). By contrast only a very small proportion of respondents found out about e-cigarettes from a youth worker (3.3%) or health professional (3.0%).
  • The majority of respondents (68.6%) have never used an e-cigarette, with 13.7% only using an e-cigarette once and just 10% currently using an e-cigarette. A higher percentage of males reported currently using e-cigarettes every day (6.8%) relative to females (2.2%).
  • Respondents from the most deprived parts of Wales were far less likely to have never used an e-cigarette (48.6%) relative to respondents located in the least deprived areas of the country (75.4%).
  • The vast majority of never smokers have also never used an e-cigarette (88.9%), with a further 8.2% only ever having tried an e-cigarette once. Just 0.6% of never smokers currently use e-cigarettes regularly (i.e. more than once a week).
  • The main reasons for using e-cigarettes for the first time were to see what they tasted like (48.7%), because friends were using them (40.1%), and for a bit of fun (30.7%). 22.1% of respondents cited using e-cigarettes to reduce their intake of tobacco cigarettes.
  • The vast majority of respondents (90.3%) who had used e-cigarettes and smoked tobacco cigarettes reported starting to smoke tobacco cigarettes first.
  • Of the respondents who had used e-cigarettes and smoked tobacco cigarettes at some point (n = 172) 25.0% smoked fewer tobacco cigarettes since starting to use e-cigarettes, with 34.3% of respondents ceasing to smoke tobacco cigarettes altogether.

Human heart cells respond less to e-cig vapour than tobacco smoke – University of Bristol

New research has showed substantial differences in the way human heart cells respond to e-cigarette vapour and conventional cigarette smoke.

Researchers from the Medical Research Council Integrative Epidemiology Unit (MRC IEU) at the University of Bristol investigated how the same type of cells as those found in the arteries of the heart, known as human coronary artery endothelial cells (HCAEC), responded when they were exposed to both e-cigarette aerosol and conventional cigarette smoke.

Their results were published in the journal Drug and Alcohol Dependence.

Professor Marcus Munafò, who was part of the study team, said: “The past few years have seen a rapid growth in the use of e-cigarettes, which deliver nicotine via inhaled aerosol. It’s thought that e-cigarettes are unlikely to be as harmful as conventional cigarettes, but little data exists to show their relative harms, or the long term effects of e-cigarette use. Therefore, research into these biological effects is critical. Our study looked at the stress response in heart cells in response to cigarette smoke and e-cigarette aerosol.”

The researchers created cigarette smoke extract from a conventional cigarette and electronic cigarette aerosol extract from an e-cigarette aerosol. Both were passed through a culture of the cells. The researchers then analysed the gene expression patterns of the heart cells to see if the cells exhibited a stress response to either the cigarette smoke or e-cigarette aerosol exposure.

Professor Munafò said: “We found the cells showed a stress response from the cigarette smoke extract, but not from the electronic cigarette aerosol extract. This result suggests tobacco smokers may be able to reduce immediate tobacco-related harm by switching from conventional cigarettes to e-cigarettes.”
